MANUFACTURE OF BOTTLE-SEALS.

To all whom it may concern Be it known that I, BENJAMIN Aonnsxcn, a citizen of the UnitedStates, residing at Brooklyn, in the county of Kings and State of New York, have invented certain now and useful Improvements in lvlanufactnre of Bottle-Seals, of which the following is a specification.

The object of this invention is to simplify and cheapen the manufacture of bottle and the like caps or seals of'the so-called Crown type, and particularly to provide a process whereby the union between the cork disks, the fusible adhesive afforded by suitably treated collets, and the shells of any run of such caps or seals turned out will be uniform and also reliable and effective. This object I accomplish by first permanently uniting the shell and disk in substantially undiminishing compressing relation to the interposed adhesive and heating the thusassembled parts at a temperature sufficient to fuse the adhesiveand thereafter cooling the parts without extraneous pressure. Preferably, the shell and disk are united permanently in substantially undiminishing compressing relation to the interposed adhesive in unfused state and then, either immediately or at some future time, the thus formed article is heated to fuse the adhesive and then cooled, the heating and cooling both. taking place without extraneous pressure.

My process is characterized by the absence of pressure derived from means extraneous of the article itself and operative during the cooling step, such pressure having certain disadvantages not present in the practice of my invention and chief among which is the disturbance if not the destruction of the sna ua non adhesion or adhesive union between disk and adhesive and adhesive and shell due to the very act of removing the pressure after the adhesive has set, which of course involves a readjustment of the molecules of the cork of the disk as the same resumes its normal shape and consequently of the now hardened or set adhesive; in its preferred form my process is characterized by the exclusion of pressure, derived from means extraneous of the article itself, upon the interposed adhesive at any time while it is in the fused state, this having the disadvantage that air entrapped in holes or crevices in the cork disk by the plunger (or other pressure medium) is fre- Specification of Letters Patent.

quently forced between areas of the disk and adhesive, leaving the latter separated to that extent in the ultimate product.

My invention hasv a positive advantage over other known methods in respect to-the saving of time, the simplifying of the apparatus for the making of the caps, and the liberty of subjecting the parts to the main steps of the treatment in immediate or non-immediate sequence, as desired.

1 now proceed to describe my invention with reference to the preferred procedure.

. Figures 1 and 2 of the accompanying drawings are a plan and a vertical sectional view of an apparatus designed for use in performing my method ;of foaning bottle caps; I

Fig. 3 is a vertical sectional view of a part of the apparatus, showing two caps or seals (in section) at different stages in the method; and,

Fig. ,4 is an enlarged fragmentary sectional View of a finished cap.

Describing first the apparatus, a is a pedestal surmounted by a fixed vertical post 6 and carrying a lateral fixed arm c supporting another fixed vertical post d.

911. the; post 6 is revoluble the hollow shaft 6 of a horizontal rotary disk or table f; on the post cl is .revoluble the hollow shaft 9 of another but similar disk or table it which somewhat overlaps the table f. The hollow shafts e and g carry fixed pulleys 0 and 9 around which extends a crossed belt -21 so that the rotation of pulley 6 will result in rotation of pulley g in the opposite direction, and hence disks f and it will revolve reversely. Any suitable means, such as the shaft j carrying a pulley 70 and geared with the hollow shaft 6 by the gearing Z, may be-employed for rotating thedisks.

m is a spider pinned or otherwise fixed to the post Z) above the disk 7 and having an annular invertedchannel n covering the pe ripheral portion of disk f excepting for a short are adjoining the disk h, where said channel is cut away. The channel for-ms with disk f a passage through which the caps are conveyed by disk fr until they come in contact with the deflector 0 arranged in a tangent of the inner wall of the channel, and by means of which they are caused to be discharged.

At a suitable point over the peripheral portion of the disk It is arranged a die p. The shells of the seals to be formed, each containing a collet of fusible material and a cork disk superimposed on the collet as shown in the upper part of Fig. 3, are one after another centered in the die and thereupon forced by a plunger 9 down through the die onto the rotating disk in In the advance of the arc-shaped line of uncompleted caps thus deposited on the disk It they one after another enter the channel n and, in the rotation of disk h, are wiped off the latter by the outer wall of the channel, being deposited on disk f to be conveyed thereby through the channel in the way described.

1" is a suitable arc-shaped burner arranged under the peripheral portion of the disk The parts which go to make up the cap include a shell A, having a corrugated or crimped flange similar to that of the ordinary so-called Crown, a cork disk B, and a collet C of, or having on both of its faces, fusible adhesive material. The parts being assembled and deposited in the aperture of the die as explained, when the plunger forces them through the aperture the flange of the shell is permanently forced inwardly or contracted into the form illustrated in the cap seen resting on the disk 72 in Fig. 3. 'ln its new shape the flange holds the cork disk B (which previously lay more or less loose in the shell) arched, exerting upward substantially uniform pressure on the collet, which in turn exerts substantially uniform pressure on the top wall of the shell. The treatment so far has been under the ordinary atmospheric temperature condition, the fusible material of the collet being in the unfused state and therefore having undergone practically no change in the form of the surface thereof which is next to the disk of cork excepting that incident to the arching thereof. The articles in this form may be kept for further treatment whenever de sired; as herein illustrated, however, they proceed at once to the next or collet-fusing step, being transferred by the rotary disk it onto the disk and thereby carried over the burner 0" through the passage formed by the channel 12, whereby the fusible adhesive material of the collet is fused. lVhile being subjected to heat in this way the presence cause such bodies are not confined and, in

place of such air bodies finding their way between the cork disk and the collet around any such hole, in the way already mentioned in connection with the manufacture of bottle caps according to the usual method, the fusible material is, rather, free to besqueezed out from between the disk and collet into the holeindicated at m in Fig. 4-. In this state the caps finally leave the disk 7 and cool, the setting of the adhesive taking place without pressure exceeding that inherent in the caps, which entails, as explained, injury to the adhesive union upon such extra pressure being afterward removed and the cork disks assuming their normal or uncompressed state.

It will be apparent that my improved process has the advantage that it not only eliminates the employment of means to keep the parts of each cap under special'control from the time they are initially brought into association with each other to the time the heated collet has cooled and set, with the waste of time that is necessarily an incident to the production of each cap made according to the usual method, but produces caps or seals the union of whose parts, being allowed to take place without interference and to remain undisturbed, is uniform and hence more reliable in character than that of the ordinary Crown cap or seal.

Having thus fully described'my invention, what I claim as new and desire to se cure by Letters Patent is:

In the manufacture of sealing caps characterizec by a metallic 's ell, a yielding packing disk contained in the shell and a fusible adhesive between the adjoining faces of the disk and top wall of the shell, the hereindescribed method consisting in first permanently uniting the shell and disk in substantially undiminishing compressing relation to the interposed adhesive and heating the thus-assembled parts at a temperature sufficient to fuse the adhesive and thereafter cooling the parts 'without extraneous pressure.

In testimony whereof I aflix my signature in presence of two witnesses. V
